Abstract

PURPOSE: To remove burr on a steel plate completely even if there is a wave on the steel plate by blowing away the burr, which is made when the side end of the steel plate is cut with a melting milling machine, after melting it with the flame of a high pressure gas burner installed diagonally opposite to the travelling steel plate.
CONSTITUTION: A frame 4 is installed on a guide post 7, which is secured to a base 8, in an adjustable manner to move up and down and back and forth by a cylinder unit or the like. A high pressure gas burner 3 is installed on the top of the vertical portion 4a of the frame 4 so that it can make a tilting motion freely and guide rollers 5, 6 for the travelling steel plate 1 are installed on the vertical portion 4a and on the horizontal portion 4b. The burner 3 has a high oxygen exhaust port in its center and the high pressure oxygen exhaust port has a combustion gas exhaust port consisting of plural numbers of small holes provided in its circumference. A relatively wide area including the burr is heated by the combustion flame formed at the combustion gas exhaust ports and the iron contents of the burr is combusted and blown away by the high pressure oxygen exhausted through the high pressure exhaust port at the enter of the burner 3.
